This motor multiplexer (MTRMX-Nx) is specifically designed medium power motor controller to connect RCX LEGO motors to NXT.

This multiplexer connects directly to one of the digital sensor ports of NXT and the power for the motors is supplied from an external source.

It's designed as Quad 35 Volt 0.6 amps H-Bridge motor drive.

This multiplexer drives 9 volt RCX compatible Lego electric motors (Lego 71427, 74569, 43362 or Electric RC Race Buggy Motor 5292).

Use this if you already have some of these motors and wish to put them to use with NXT. If you don't have these motors, we suggest NXTMMX or NXTServo.
